近年、ビルなどの建物におけるフロアー構造は、通信技術などの発達により床下にネットワークケーブルやその他各種ケーブルを配線するために、床面（床下）との間に空間を設けてフロアパネルを所定高さ位置に敷設した二重床構造とされることが多い。この二重床構造とするには、フロアパネルを床面から浮かせて支えるための支柱が必要になる（例えば、特許文献１、２など参照）。   In recent years, floor structures in buildings such as buildings have a predetermined height by providing a space between the floor and the floor (under the floor) in order to route network cables and other various cables under the floor due to the development of communication technology. It is often a double floor structure laid at the location. In order to make this double floor structure, a support for floating and supporting the floor panel from the floor surface is required (see, for example, Patent Documents 1 and 2).

図６から図９は、従来の二重床用支柱構造の一例を示す図である。この二重床用支柱構造は、床面１００に載置されるベース部１０１と、このベース部１０１の略中央に下端部をかしめて取り付けられた円筒形状の脚部１０２と、この脚部１０２の内周面に形成された雌ネジ部１０３と螺合する雄ネジ部１０４を有し、当該脚部１０２に挿入されてその高さ位置を調整自在とするパネル支持ボルト１０５と、このパネル支持ボルト１０５の先端にかしめて取り付けられたパネル受け部材１０６と、このパネル受け部材１０６の上に載置させたフロアパネル１０７を当該パネル受け部材１０６に固定させるためのパネル固定部材１０８と、パネル受け部材１０６の高さ位置を固定する固定レバー１０９とから構成されている。   6 to 9 are diagrams showing an example of a conventional double floor support structure. This double-floor support structure includes a base portion 101 placed on the floor surface 100, a cylindrical leg portion 102 attached by caulking the lower end to the approximate center of the base portion 101, and the leg portion 102. A panel supporting bolt 105 having a male threaded portion 104 screwed with a female threaded portion 103 formed on the inner peripheral surface thereof, and being inserted into the leg portion 102 so that its height position can be adjusted, and the panel supporting bolt A panel receiving member 106 caulked to the tip of the bolt 105, a panel fixing member 108 for fixing the floor panel 107 placed on the panel receiving member 106 to the panel receiving member 106, a panel receiving The fixing lever 109 is configured to fix the height position of the member 106.

ベース部１０１は、略正方形とされた鋼板の表面にメッキを施したプレートとして形成されている。このベース部１０１には、二重床用支柱構造を床面１００に安定して載置すべく底面（載置面）をフラット化するように、下方へ突出する略環状のリブ１１０を形成している。このベース部１０１では、脚部１０２から離れた位置に形成された略環状のリブ１１０と外周下端部とを床面１００に接触させることにより、二重床用支柱構造を支持させている。   The base portion 101 is formed as a plate obtained by plating the surface of a substantially square steel plate. The base portion 101 is formed with a substantially annular rib 110 that protrudes downward so that the bottom surface (mounting surface) is flattened so that the double floor column structure can be stably mounted on the floor surface 100. ing. The base portion 101 supports the double-floor strut structure by bringing the substantially annular rib 110 formed at a position away from the leg portion 102 and the outer peripheral lower end portion into contact with the floor surface 100.

脚部１０２は、円筒形状とされた鋼板の表面にメッキを施した支柱として形成されている。この脚部１０２は、ベース部１０１の略中央に形成された孔部１１１に下端部１０２ａを挿入させ、その下端部１０２ａを当該孔部１１１の外周縁部にかしめることにより、前記ベース部１０１に対して立設固定されている。この脚部１０２の内面には、その軸方向に沿って雌ネジ部１０３が形成されている。なお、脚部１０２は、ベース部１０１に対して溶接によって固定されていてもよい。   The leg portion 102 is formed as a support column in which the surface of a cylindrical steel plate is plated. The leg portion 102 is formed by inserting a lower end portion 102a into a hole portion 111 formed substantially at the center of the base portion 101, and caulking the lower end portion 102a to the outer peripheral edge portion of the hole portion 111. It is fixed upright against. A female screw portion 103 is formed on the inner surface of the leg portion 102 along the axial direction thereof. Note that the leg portion 102 may be fixed to the base portion 101 by welding.

パネル支持ボルト１０５は、前記脚部１０２に形成された雌ネジ部１０３と螺合する雄ネジ部１０４をその外周面に有し、それら雌ネジ部１０３と雄ネジ部１０４を螺合させることによって脚部１０２に対する高さ位置を調整自在としている。また、このパネル支持ボルト１０５は、パネル受け部材１０６の下面に形成された取付孔部１１２に先端部１０５ａを挿入させ、その先端部１０５ａを取付孔部１１２の外周縁部にかしめることにより、前記パネル受け部材１０６を固定させている。   The panel support bolt 105 has a male screw portion 104 screwed to the female screw portion 103 formed on the leg portion 102 on the outer peripheral surface thereof, and the female screw portion 103 and the male screw portion 104 are screwed together. The height position with respect to the leg 102 is adjustable. Further, the panel support bolt 105 is inserted into the mounting hole 112 formed on the lower surface of the panel receiving member 106, and the front end 105a is caulked to the outer peripheral edge of the mounting hole 112. The panel receiving member 106 is fixed.

パネル受け部材１０６は、フロアパネル１０７を載置させるパネル載掛部１１３を有した円盤形状の本体部１１４と、この本体部１１４の中央に上方へ突出する円筒形状の突出部１１５とから形成されている。このパネル固定部材１０６は、先のベース部１０１及び脚部１０２と同様に鋼板の表面にメッキを施して形成されている。   The panel receiving member 106 is formed of a disk-shaped main body 114 having a panel mounting portion 113 on which the floor panel 107 is placed, and a cylindrical protrusion 115 protruding upward in the center of the main body 114. ing. The panel fixing member 106 is formed by plating the surface of the steel plate in the same manner as the base portion 101 and the leg portion 102.

本体部１１４の上面には、フロアパネル１０７の下面に形成された位置決め孔１１６に挿入係合する高さの低い截頭円形状をなす係合突起部１１７が形成されている。パネル載掛部１１３は、係合突起部１１７を除く本体部１１４の上面とされ、フロアパネル下面を載置させることにより当該フロアパネル１０７を載置支持する。なお、このパネル受け部材１０６には、４枚のフロアパネル１０７を載置させることから前記係合突起部１１７を４箇所に形成している。   On the upper surface of the main body 114, there is formed an engaging projection 117 having a truncated fringe shape that is inserted and engaged with a positioning hole 116 formed in the lower surface of the floor panel 107. The panel mounting portion 113 is an upper surface of the main body portion 114 excluding the engaging protrusion 117, and places and supports the floor panel 107 by placing the lower surface of the floor panel. Since the four floor panels 107 are placed on the panel receiving member 106, the engagement protrusions 117 are formed at four locations.

突出部１１５には、フロアパネル１０７の外周縁に形成された引掛部１１８を係合させる係合突起部１１９が形成されている。この係合突起部１１９は、円環状の突起として形成され、先端が下方へ折り曲がったフロアパネル１０７の引掛部１１８を係合させる。   The protrusion 115 is formed with an engagement protrusion 119 that engages a hook 118 formed on the outer peripheral edge of the floor panel 107. The engagement protrusion 119 is formed as an annular protrusion, and engages the hook 118 of the floor panel 107 whose tip is bent downward.

パネル固定部材１０８は、フロアパネル１０７の引掛部１１８を前記係合突起部１１９とで挟持させて当該フロアパネル１０７を前記パネル受け部材１０６に固定させるためのパネル押圧部１２０と、パネル支持ボルト１０５の先端部に軸芯方向へ向かって形成された穴部の周面に設けられた雌ネジ部１２１と螺合する雄ネジ部１２２を外周面に形成した締め付けボルト１２３とからなる。   The panel fixing member 108 includes a panel pressing portion 120 for fixing the floor panel 107 to the panel receiving member 106 by holding the hooking portion 118 of the floor panel 107 with the engaging protrusion 119, and the panel support bolt 105. And a fastening bolt 123 having a male screw portion 122 formed on the outer peripheral surface thereof, which is screwed with a female screw portion 121 provided on the peripheral surface of the hole portion formed in the axial direction at the tip end portion.

パネル押圧部１２０は、円盤形状をなし、その下端側外周面１２０ａを引掛部１１８に当接させ、この引掛部１１８を前記係合突起部１１９とにより上下方向から挟み込むようになっている。締め付けボルト１２３は、パネル押圧部１２０の中心部に貫通して形成された孔部１２４に挿入され、その雄ネジ部１２２をパネル支持ボルト１０５の穴部周面に形成された雌ネジ部１２１と螺合させることにより、当該パネル支持ボルト１０５に対して着脱自在とされている。この締め付けボルト１２３の基端部には、ドライバーによってパネル押圧部１２０をパネル支持ボルト１０５の穴部にねじ込むためのネジ回し溝１２５が形成されている。   The panel pressing portion 120 has a disk shape, and a lower end side outer peripheral surface 120a is brought into contact with the hooking portion 118, and the hooking portion 118 is sandwiched by the engaging projection portion 119 from above and below. The fastening bolt 123 is inserted into a hole 124 formed through the center of the panel pressing portion 120, and the male screw portion 122 is connected to the female screw portion 121 formed on the hole peripheral surface of the panel support bolt 105. By being screwed together, the panel support bolt 105 is detachable. A screw driving groove 125 for screwing the panel pressing portion 120 into the hole of the panel support bolt 105 by a screwdriver is formed at the base end portion of the tightening bolt 123.

固定レバー１０９は、パネル支持ボルト１０５の外周面に形成された雄ネジ部１０４と螺合する雌ネジ部１２６を有した固定部１２７と、この固定部１２７から延在して形成されるスリット１２８を有したハンドル部１２９とからなる。この固定レバー１０９は、ハンドル部１２９を回して脚部１０２の上端面に固定部１２７を圧接させることにより、所定高さに仮位置決めされたパネル受け部材１０６の高さ位置を確実に固定させ、当該パネル受け部材１０６を回転不可能な状態とする。   The fixing lever 109 includes a fixing portion 127 having a female screw portion 126 screwed with the male screw portion 104 formed on the outer peripheral surface of the panel support bolt 105, and a slit 128 formed extending from the fixing portion 127. And a handle portion 129 having The fixing lever 109 securely fixes the height position of the panel receiving member 106 temporarily positioned at a predetermined height by rotating the handle portion 129 and press-contacting the fixing portion 127 to the upper end surface of the leg portion 102. The panel receiving member 106 is brought into a non-rotatable state.

なお、パネル固定部材１０８及び固定レバー１０９も同様に鋼板の表面にメッキを施すことによって形成されている。   Similarly, the panel fixing member 108 and the fixing lever 109 are formed by plating the surface of the steel plate.

二重床フロアー構造とするためには、先ず、上記のように構成された二重床用支柱構造を床面１００に配置する。そして、フロアパネル１０７を床面１００から所定高さＨ１となるようにパネル受け部材１０６を回転させる。パネル受け部材１０６を回転させることにより、パネル支持ボルト１０５と脚部１０２の雌ネジ部１０３と雄ネジ部１０４とが螺合して該パネル受け部材１０６の高さが調整される。   In order to obtain a double floor structure, first, the double floor support structure configured as described above is arranged on the floor surface 100. And the panel receiving member 106 is rotated so that the floor panel 107 may become predetermined height H1 from the floor surface 100. FIG. By rotating the panel receiving member 106, the panel supporting bolt 105, the female screw portion 103 of the leg portion 102, and the male screw portion 104 are screwed together to adjust the height of the panel receiving member 106.

次に、このままでは、パネル受け部材１０６は、脚部１０２に対して回転してしまうため、ハンドル部１２９を回転させて当該パネル受け部材１０６を回転不可能な状態にロックする。ロックするに当たっては、図１０に示すように、金槌１３０でハンドル部１２９を変形するまで叩く。これにより、パネル固定部材１０６は、確実にロックされることになる。   Next, since the panel receiving member 106 rotates with respect to the leg portion 102 as it is, the handle portion 129 is rotated to lock the panel receiving member 106 in a non-rotatable state. In locking, as shown in FIG. 10, the handle portion 129 is hit with a hammer 130 until it is deformed. Thereby, the panel fixing member 106 is securely locked.

そして、パネル受け部材１０６が所定高さＨ１となったところで、フロアパネル１０７の引掛部１１８を係合突起部１１９に係合させると共に、該フロアパネル１０７の下面に形成された位置決め孔１１６を前記係合突起部１１７に挿入させる。すると、フロアパネル１０７は、パネル受け部材１０６のパネル載掛部１１３上に位置決めされて載置される。   Then, when the panel receiving member 106 reaches the predetermined height H1, the hook 118 of the floor panel 107 is engaged with the engaging protrusion 119, and the positioning hole 116 formed on the lower surface of the floor panel 107 is provided with the positioning hole 116. The engagement protrusion 117 is inserted. Then, the floor panel 107 is positioned and placed on the panel mounting portion 113 of the panel receiving member 106.

次いで、ドライバーなどを用いてパネル固定部材１０８をパネル支持ボルト１０５にねじ込み、パネル押圧部１２０を引掛部１１８に押し当てる。すると、引掛部１１８は、係合突起部１１９とパネル押圧部１２０とで挟持されるため、前記フロアパネル１０７は位置ずれを生じることなく固定される。   Next, the panel fixing member 108 is screwed into the panel support bolt 105 using a screwdriver or the like, and the panel pressing portion 120 is pressed against the hooking portion 118. Then, since the hooking portion 118 is sandwiched between the engaging projection portion 119 and the panel pressing portion 120, the floor panel 107 is fixed without causing a positional shift.

以上の工程を順次行うことで、床面１００との間に床下空間を持たせた二重床フロアーを構築することができる。

ところで、上述のように構成された二重床用支柱構造では、部品点数が多いため、各部品をかしめたり、溶接したりするなど、組立工数に相当の時間及び費用がかかる。また、各構成部品は、鋼板にメッキを施すことによって形成されるため、コスト増が避けられない。   By the way, in the double floor support structure configured as described above, since the number of parts is large, it takes considerable time and cost to assemble the parts, such as caulking or welding each part. Moreover, since each component is formed by plating a steel plate, an increase in cost is inevitable.

また、メッキ仕上げをすることによって、ウィスカ（Ｓｎ、Ｚｎなどの低融点金属めっきから成長する針状の単結晶）の発生や六価クロム含有から避けることは困難となる。さらには、鋼板によって各構成部品を形成しているので、パネル・支柱組立状態の耐荷重性能試験では「全変形量＝フロアパネルの変形量＋支柱のたわみ量」となるから、支柱のたわみ量が大きい鋼材支柱の場合は全たわみ量が大きくなる傾向にある。   In addition, it is difficult to avoid the occurrence of whiskers (acicular single crystals grown from low melting point metal plating such as Sn and Zn) and hexavalent chromium by plating. Furthermore, since each component is made of steel plate, the total amount of deformation = amount of deformation of the floor panel + amount of deflection of the column in the load-bearing performance test of the panel and column assembly state. In the case of a steel column having a large thickness, the total deflection tends to increase.

また、この二重床用支柱構造では、パネル受け部材１０６が緩まないように固定レバー１０９を使用し、その固定レバー１０９を金槌１３０で叩いて一定の締め付けトルクで締め付けるため、レバー締め付け作業時に大きな金属打音が発生し騒音の原因になる。   Further, in this double floor support structure, the fixing lever 109 is used so that the panel receiving member 106 does not loosen, and the fixing lever 109 is struck with a hammer 130 and tightened with a constant tightening torque. Metal hitting sound is generated, causing noise.

また、前記二重床用支柱構造では、図９に示すように、支柱軸芯から遠い位置（中心から距離Ｌ１）でフロアパネル１０７を受けているため、スラブによってはパネル間段差が大きくなる傾向にある。また、ベース部１０１に対して脚部１０２をかしめることにより固定させているため、ベース部１０１と脚部１０２の垂直度を確保することは難しく、脚部１０２が傾いている場合にはパネル間段差の原因になる。   Moreover, in the said double floor support | pillar structure, as shown in FIG. 9, since the floor panel 107 is received in the position (distance L1 from a center) far from a support | pillar axis, the level | step difference between panels tends to become large depending on slab. It is in. In addition, since the leg portion 102 is fixed to the base portion 101 by caulking, it is difficult to ensure the perpendicularity between the base portion 101 and the leg portion 102. If the leg portion 102 is inclined, the panel Causes a gap.

また、この二重床用支柱構造では、ベース部１０１の下面に接着剤を塗布して床面１００に固定させるが、ベース部１０１の下面に形成した環状のリブ１１０による凹部に接着剤が入り込んで当該接着剤の厚みが厚くなることから、本来薄く均一に塗布することにより接着力は高まるが、逆に接着力は弱まる傾向となっている。このため、有効接着面積が減少し、接着力をアップさせるべく接着面積を大きくしなければならなかった。   Further, in this double floor support structure, an adhesive is applied to the lower surface of the base portion 101 and fixed to the floor surface 100, but the adhesive enters a recess formed by the annular rib 110 formed on the lower surface of the base portion 101. Since the adhesive becomes thicker, the adhesive strength is increased by applying it thinly and uniformly, but the adhesive strength tends to be weakened. For this reason, the effective adhesion area has decreased, and the adhesion area has to be increased in order to increase the adhesion.

そこで、本発明は、部品点数の削減を図り組立工数並びに低コスト化を実現し、さらには、耐荷重性能の向上、及びウィスカフリー並びに六価クロムレスを実現し得る二重床用支柱構造を提供することを目的とする。   Accordingly, the present invention provides a double-floor support structure that can reduce the number of parts, realize assembly man-hours and cost reduction, improve load bearing performance, and realize whisker-free and hexavalent chromium-free. The purpose is to do.

本発明の二重床用支柱構造は、床面に載置されるベース部と、このベース部に一体化されて立設し、先端部に第１螺合部を有すると共に外周面に第２螺合部を有した脚部と、を有した支柱ベースと、フロアパネルのコーナー部に形成された引掛部を段差部で引っ掛けて該フロアパネルをパネル載置面に載置させるパネル載掛部と、該パネル載掛部間に呈し且つ該フロアパネルのコーナー下面に対して隙間を有して該コーナー下面を載置させるパネル補助受け部と、前記脚部の第２螺合部と螺合して前記支柱ベースに対する高さ位置を調整自在とする第３螺合部と、を有したパネル受け部材と、前記引掛部を前記パネル載掛部の段差部に押し付け挟持して固定するパネル押圧部と、前記第１螺合部と螺合して該パネル押圧部の高さ位置を調整自在とする第４螺合部と、を有したパネル固定部材と、前記脚部の第２螺合部と螺合する第５螺合部を有した固定部と、この固定部に一体化されたレバー部とを有し、前記固定部を前記パネル受け部材に当接させて前記支柱ベースに対する該パネル受け部材の高さ位置を固定させる固定部材とを備えたことを特徴とする。 The double-floor support structure of the present invention has a base portion placed on the floor surface, and is erected integrally with the base portion, and has a first threaded portion at the tip portion and a second on the outer peripheral surface. A support base having a leg portion having a threaded portion, and a panel mounting portion for hooking a hook portion formed at a corner portion of the floor panel at a stepped portion to place the floor panel on the panel mounting surface. And a panel auxiliary receiving portion that is placed between the panel mounting portions and has a gap with respect to the corner lower surface of the floor panel to place the corner lower surface, and the second screwing portion of the leg portion and screwing and a third and a threaded portion, a panel receiving member having a panel pressing and fixing by clamping pressing the hook portion to the step portion of the panel Nokaka unit for freely adjusting the height position relative to the strut base To adjust the height position of the panel pressing portion by screwing with the first screwing portion. A panel fixing member having a fourth screwing portion, a fixing portion having a fifth screwing portion screwed with the second screwing portion of the leg portion, and a single fixing portion. And a fixing member that fixes the height position of the panel receiving member with respect to the column base by bringing the fixing portion into contact with the panel receiving member.

本発明の二重床用支柱構造によれば、ベース部と脚部とを一体化した支柱ベースと、この支柱ベースに対してその高さ位置を調整自在とするパネル受け部材と、所望の高さ位置に設定されたパネル受け部材とでフロアパネルを挟持して固定するパネル固定部材と、その所望高さ位置にあるパネル受け部材の位置を固定する固定部材とからなる僅か４つの構成部品からなるので、大幅に部品点数を削減することができると共に組立工数も減らすことができ、低コスト化を実現できる。   According to the double floor support structure of the present invention, the support base in which the base portion and the leg portion are integrated, the panel receiving member whose height position is adjustable with respect to the support base, the desired height, A panel fixing member that clamps and fixes the floor panel with the panel receiving member set in the vertical position, and a fixed member that fixes the position of the panel receiving member at the desired height position. As a result, the number of parts can be greatly reduced, the number of assembly steps can be reduced, and the cost can be reduced.

本実施の形態の二重床用支柱構造は、図１から図３に示すように、支柱ベース１と、この支柱ベース１に取り付けられるパネル受け部材２と、このパネル受け部材２にフロアパネルを固定させるパネル固定部材３と、支柱ベース１に対するパネル受け部材２の高さ位置を固定する固定部材４とから構成されている。   As shown in FIGS. 1 to 3, the double floor support structure of the present embodiment includes a support base 1, a panel receiving member 2 attached to the support base 1, and a floor panel attached to the panel receiving member 2. A panel fixing member 3 to be fixed and a fixing member 4 to fix the height position of the panel receiving member 2 with respect to the column base 1 are configured.

「支柱ベース」
支柱ベース１は、図３及び図４に示すように、床面５に載置されるベース部６と、このベース部６に一体化されて立設する脚部７とから構成されている。かかる支柱ベース１は、機械的強度の高いアルミダイキャストによって一体的に形成されている。 "Prop base"
As shown in FIGS. 3 and 4, the column base 1 includes a base portion 6 placed on the floor surface 5 and leg portions 7 that are integrated with the base portion 6 and are erected. The support base 1 is integrally formed by aluminum die casting having high mechanical strength.

ベース部６は、図２（Ｂ）、図３及び図４（Ｂ）で示すように、床面５に対し安定して密着するように、底面６ａを略平坦面とした正方形状としている。かかるベース部６の底面６ａを平坦面とすれば、接着剤を薄く均一なものとすることができるから床面５に対する接着強度を大幅に向上させることができる。これに対して、鋼板からなる従来のベース部６では、底面６ａに環状のリブを形成したことにより接着剤の塗布厚が厚くなって接着強度が低下するため、接着面積を確保すべくベース部６を大きくする必要があった。しかしながら、本実施の形態では、従来の大きさよりも小さなベースサイズで十分な接合強度を確保することができることからコストダウンを実現できる。   As shown in FIGS. 2 (B), 3 and 4 (B), the base 6 has a square shape with a bottom surface 6a having a substantially flat surface so as to be stably adhered to the floor surface 5. If the bottom surface 6a of the base portion 6 is a flat surface, the adhesive can be made thin and uniform, so that the adhesive strength to the floor surface 5 can be greatly improved. On the other hand, in the conventional base portion 6 made of a steel plate, the annular rib is formed on the bottom surface 6a, so that the thickness of the adhesive is increased and the adhesive strength is lowered. 6 had to be increased. However, in the present embodiment, it is possible to reduce the cost because sufficient bonding strength can be ensured with a base size smaller than the conventional size.

また、このベース部６は、機械的強度を高めるべく外周部から脚部７へと向かうに従ってその厚みを次第に厚くしている。さらに、このベース部６の各コーナー部分８は、角部を円弧形状に丸めたＲ形状としている。このため、フロアパネルを敷設する施工中に誤ってこの二重床用支柱構造を床面（スラブ）５に落下させてしまった場合でも、十分な厚みとコーナー部分８のＲ形状によって支柱ベース１が破壊するのが防止される。   Further, the base portion 6 gradually increases in thickness as it goes from the outer peripheral portion to the leg portion 7 in order to increase the mechanical strength. Further, each corner portion 8 of the base portion 6 has an R shape in which a corner portion is rounded into an arc shape. For this reason, even if this double floor support structure is accidentally dropped onto the floor surface (slab) 5 during the construction of laying the floor panel, the support base 1 has sufficient thickness and the R shape of the corner portion 8. Is prevented from being destroyed.

また、ベース部６には、この二重床用支柱構造を床面５に対して確実に固定させるために、ボルトを挿通させるボルト挿通孔９が形成されている。ボルト挿通孔９は、ベース部６の各コーナー部分８の近傍部に円形孔として貫通形成されている。   In addition, a bolt insertion hole 9 through which a bolt is inserted is formed in the base portion 6 in order to securely fix the double floor support structure to the floor surface 5. The bolt insertion hole 9 is formed as a circular hole in the vicinity of each corner portion 8 of the base portion 6.

脚部７は、図３及び図４に示すように、先端からベース部６へと向かうに従ってその直径を次第に大きくする略円筒形状をなし、該ベース部６に対し垂直に立設されている。この脚部７は、アルミダイキャストによってベース部６と一体的に形成されているので、従来のようなかしめや溶接などによって固定されるものではないから該ベース部６に対する立設角度は一定に保たれる。これにより、本実施の形態の二重床用支柱構造で支持載置させたフロアパネル間に発生する段差を大幅に減少させることができる。   As shown in FIGS. 3 and 4, the leg portion 7 has a substantially cylindrical shape in which the diameter gradually increases from the tip toward the base portion 6, and is erected vertically with respect to the base portion 6. Since the leg portion 7 is integrally formed with the base portion 6 by aluminum die casting, the standing angle with respect to the base portion 6 is constant because it is not fixed by caulking or welding as in the prior art. Kept. Thereby, the level | step difference which generate | occur | produces between the floor panels supported and mounted by the support structure for double floors of this Embodiment can be reduced significantly.

そして、この脚部７には、その先端部にパネル固定部材３を挿入螺合させる孔部１０が形成され、その孔部１０の内周面に第１螺合部である雌ネジ部１１が形成されている。また、この脚部７の先端側外周面には、パネル受け部材２と螺合して前記支柱ベース１に対する該パネル受け部材２の取り付け高さ位置を調整自在とするための第２螺合部である雄ネジ部１２が形成されている。この雄ネジ部１２の一部には、ネジ山が削り取られて平坦とされた平坦面１３が形成されている。この平坦面１３は、相対向する位置に２箇所形成されており、後述する固定部材４を回すときに支柱ベース１を工具で押さえる際の工具押さえ部として機能する。   The leg 7 is formed with a hole 10 into which the panel fixing member 3 is inserted and screwed at the tip thereof, and a female screw part 11 as a first screwing part is formed on the inner peripheral surface of the hole 10. Is formed. Also, a second threaded portion for allowing the mounting height position of the panel receiving member 2 to be adjusted with respect to the column base 1 by being screwed with the panel receiving member 2 on the front end side outer peripheral surface of the leg portion 7. The male screw portion 12 is formed. A part of the male screw part 12 is formed with a flat surface 13 which is flattened by cutting off a screw thread. The flat surfaces 13 are formed at two positions facing each other, and function as a tool pressing portion when pressing the column base 1 with a tool when a fixing member 4 described later is rotated.

そして、この支柱ベース１には、脚部７からベース部６にかけて補強用のリブ１４が複数形成されている。かかるリブ１４は、脚部７の略中央高さ位置からベース部６の表面６ｂへと傾斜する略三角形状の鍔部として当該脚部７を４等分する位置に設けられている。このリブ１４を設けたことにより、支柱ベース１の機械的強度を大幅に高めることができる。   A plurality of reinforcing ribs 14 are formed on the support base 1 from the leg portion 7 to the base portion 6. The rib 14 is provided at a position that divides the leg portion 7 into four as a substantially triangular collar portion that is inclined from the substantially central height position of the leg portion 7 to the surface 6 b of the base portion 6. By providing this rib 14, the mechanical strength of the column base 1 can be significantly increased.

このようにアルミダイキャストによってベース部６と脚部７を一体的に形成した支柱ベース１では、例えば耐震入力加速度１Ｇに耐え得る程度の直径とした脚部７と、次第に厚みを厚く且つ接着強度を確保するのに必要最低限必要な面積を持ったベース部６とから構成されるので、支柱ベース１のたわみ量を従来の鋼板からなる支柱に対して大幅に減少させることができる。例えば、パネル・支柱組立状態での耐荷重性能を約３０％向上させることができる。これにより、フロアパネルの板厚の薄板化が可能となり軽量化を実現することができる。   Thus, in the column base 1 in which the base part 6 and the leg part 7 are integrally formed by aluminum die casting, for example, the leg part 7 having a diameter that can withstand the seismic input acceleration 1G, the thickness is gradually increased, and the adhesive strength is increased. Therefore, the amount of deflection of the support base 1 can be greatly reduced compared to a support made of a conventional steel plate. For example, the load bearing performance in the panel / post assembly state can be improved by about 30%. As a result, the thickness of the floor panel can be reduced, and the weight can be reduced.

「パネル受け部材」
パネル受け部材２は、図５に示すように、支柱ベース１に螺合してその高さ位置を調整自在としフロアパネル１５を床面５から所定高さＨに載置支持するもので、フロアパネル１５を載置させるフロアパネル載置部１６と、このフロアパネル載置部１６に一体化され支柱ベース１に螺合される取付螺合部１７とからなる。このパネル受け部材２は、支柱ベース１と同様、機械的強度の高いアルミダイキャストによって一体的に形成されている。 "Panel receiving member"
As shown in FIG. 5, the panel receiving member 2 is screwed into the support base 1 so that its height position can be adjusted, and the floor panel 15 is placed and supported at a predetermined height H from the floor surface 5. It comprises a floor panel placement portion 16 on which the panel 15 is placed, and a mounting screw portion 17 that is integrated with the floor panel placement portion 16 and screwed into the column base 1. The panel receiving member 2 is integrally formed by aluminum die casting having high mechanical strength, like the column base 1.

フロアパネル載置部１６は、図１及び図２に示すように、本体部１８と、この本体部１８の上面に突出する４箇所のパネル載掛部１９と、これら各パネル載掛部１９間に呈する前記本体部１８の上面であるパネル補助受け部２０とからなる。   As shown in FIGS. 1 and 2, the floor panel mounting portion 16 includes a main body portion 18, four panel mounting portions 19 projecting from the upper surface of the main body portion 18, and a space between these panel mounting portions 19. And a panel auxiliary receiving portion 20 which is the upper surface of the main body portion 18.

本体部１８は、外周面のうち４箇所を直線とした略円盤体として形成され、上面側にパネル載掛部１９を形成し、下面側に取付螺合部１７を形成している。   The main body 18 is formed as a substantially disc body having four straight lines on the outer peripheral surface, the panel mounting portion 19 is formed on the upper surface side, and the mounting screw 17 is formed on the lower surface side.

パネル載掛部１９は、本体部１８の外周面を直線とした４箇所の位置に対応して設けられ、略矩形状をなす突起部として形成されている。また、これら４つのパネル載掛部１９は、前記した脚部７をパネル受け部材２の中心に形成した貫通孔２１の周囲を取り囲む円環壁部２２によって連結一体化されている。このパネル載掛部１９は、前記円環壁部２２よりも一段高い突起部とされ、平坦面とする上面をフロアパネル１５のコーナー部分を載置させるパネル載置面２３としている。   The panel mounting part 19 is provided corresponding to four positions where the outer peripheral surface of the main body part 18 is a straight line, and is formed as a projecting part having a substantially rectangular shape. Further, these four panel mounting portions 19 are connected and integrated by an annular wall portion 22 surrounding the periphery of the through hole 21 formed with the leg portion 7 at the center of the panel receiving member 2. The panel mounting portion 19 is a projection that is one step higher than the annular wall portion 22, and has a flat upper surface as a panel mounting surface 23 on which the corner portion of the floor panel 15 is mounted.

このパネル載置面２３には、ゴムなどからなる緩衝部材であるクッションラバー２４が取り付けられている。クッションラバー２４は、フロアパネル１５と二重床用支柱構造との間の緩衝材として機能すると共に、金属同士の接触音を防止し且つフロアパネル１５上を歩行する歩行時に発生する反響音を緩和させる効果を奏する。また、このクッションラバー２４は、亜鉛めっき鋼板からなるフロアパネル１５とアルミダイキャストからなるパネル受け部材２との異種金属接触による腐食を防止する。   A cushion rubber 24 that is a buffer member made of rubber or the like is attached to the panel mounting surface 23. The cushion rubber 24 functions as a cushioning material between the floor panel 15 and the double-floor support structure, prevents contact sounds between metals, and mitigates reverberation generated during walking while walking on the floor panel 15. Has the effect of making Further, the cushion rubber 24 prevents corrosion caused by different metal contact between the floor panel 15 made of galvanized steel plate and the panel receiving member 2 made of aluminum die cast.

また、このパネル載掛部１９の内側面１９ａは、フロアパネル１５のコーナー部分の形状に応じて円弧形状とされると共に、パネル載置面２３から円環壁部２２の上面２２ａへと向かって傾斜する傾斜面とされている。このパネル載掛部１９の内側面１９ａと円環壁部２２の上面２２ａとで形成される空間部に、前記フロアパネル１５のコーナー部分に下方へ折曲形成された引掛部２５が配置される。この空間部に配置された引掛部２５は、パネル載掛部１９の段差形状とされた段差部２８に係合されることになる。この段差部２８は、フロアパネル１５の引掛部２５を載せ掛ける主たるパネル受け部として機能する。   Further, the inner side surface 19 a of the panel mounting portion 19 has an arc shape according to the shape of the corner portion of the floor panel 15, and is directed from the panel mounting surface 23 toward the upper surface 22 a of the annular wall portion 22. The inclined surface is inclined. In the space formed by the inner side surface 19a of the panel mounting portion 19 and the upper surface 22a of the annular wall portion 22, a hooking portion 25 that is bent downward at the corner portion of the floor panel 15 is disposed. . The hooking portion 25 arranged in the space portion is engaged with the stepped portion 28 having the stepped shape of the panel mounting portion 19. The step portion 28 functions as a main panel receiving portion on which the hook portion 25 of the floor panel 15 is placed.

また、このパネル載掛部１９の内側面１９ａには、フロアパネル１５が水平方向において位置ずれを生じないように防止するためのパネル位置ずれ防止突起部２６が形成されている。かかるパネル位置ずれ防止突起部２６は、パネル載置面２３上に設けたクッションラバー２４の高さよりも若干突出した高さに形成されており、フロアパネル１５の引掛部２５との接触により当該フロアパネル１５の位置ずれを防止する。   Further, on the inner side surface 19 a of the panel mounting portion 19, a panel misalignment prevention protrusion 26 for preventing the floor panel 15 from being displaced in the horizontal direction is formed. The panel misalignment prevention protrusion 26 is formed at a height that slightly protrudes from the height of the cushion rubber 24 provided on the panel placement surface 23, and is brought into contact with the hook portion 25 of the floor panel 15. Misalignment of the panel 15 is prevented.

なお、パネル載掛部１９の外側面には、パネル載置面２３から下方へ向かって前記本体部１８との連結部手前の位置まで平面コ字状の縦溝２７が形成されている。   Note that a U-shaped vertical groove 27 is formed on the outer surface of the panel mounting portion 19 from the panel mounting surface 23 to a position before the connecting portion with the main body portion 18 from the lower side.

パネル補助受け部２０は、各パネル載掛部１９間に呈する扇形状をなす本体部１８の一部として形成されている。このパネル補助受け部２０は、フロアパネル１５のコーナー下面１５ａに対して若干の隙間Ｓ（図５参照）を持ち、終局荷重付近で該フロアパネル１５のコーナー下面１５ａを支えるようになっている。このように、フロアパネル１５を主として段差部２８で引っ掛けてパネル載置面２３に載置させると共に、パネル補助受け部２０でフロアパネル１５のコーナー下面１５ａを支える構造としているので、例えば台車の繰り返し走行などで負荷が局所的に掛かった場合でも、フロアパネル１５のコーナー部分の破損を回避することができる。   The panel auxiliary receiving portion 20 is formed as a part of the fan-shaped main body portion 18 that is present between the panel mounting portions 19. The panel auxiliary receiving portion 20 has a slight gap S (see FIG. 5) with respect to the corner lower surface 15a of the floor panel 15, and supports the corner lower surface 15a of the floor panel 15 near the ultimate load. Thus, the floor panel 15 is mainly hooked by the step portion 28 and placed on the panel placement surface 23, and the panel auxiliary receiving portion 20 supports the corner lower surface 15a of the floor panel 15. Even when a load is locally applied during traveling or the like, breakage of the corner portion of the floor panel 15 can be avoided.

また、フロアパネル１５は、引掛部２５を段差部２８に引っ掛けるようにしてパネル載置面２３に載せ、後述のパネル固定部材３とによってこの引掛部２５を挟持して固定されるつば受け構造であるので、フロアパネル１５を敷設する施工スピードを速めることができる。従来は、フロアパネル１５の下面（底面）を支える底受け構造であったため、固定用レバーを所定トルクまで締め付ける必要があったが、本構造ではその必要が無くなる。   The floor panel 15 has a brim receiving structure in which the hooking portion 25 is placed on the panel mounting surface 23 so as to be hooked on the stepped portion 28, and the hooking portion 25 is sandwiched and fixed by the panel fixing member 3 described later. Therefore, the construction speed for laying the floor panel 15 can be increased. Conventionally, since it was a bottom receiving structure that supports the lower surface (bottom surface) of the floor panel 15, it was necessary to tighten the fixing lever to a predetermined torque, but this structure eliminates the necessity.

また、つば受け構造であるので、各パネル載掛部１９に載掛けされる隣り合うパネル間段差は、フロアパネル１５の板厚分の差しか発生しない。従来の底受け構造では、フロアパネル１５全体の厚みがそのまま段差として発生する。特に、フロアパネル１５の厚みはばらつき易いので、従来構造では段差が出やすかったが、本構造では段差が出難い。なお、板厚の異なる３０００Ｎパネルと５０００Ｎパネルが隣接する場合は、板厚差分のスペーサをパネル載置面２３とクッションラバー２４との間に挟み込むことで、これらパネル間を面一とすることが簡単にできる。   In addition, since the structure is a collar receiving structure, the step between adjacent panels placed on each panel placing portion 19 occurs only as much as the thickness of the floor panel 15. In the conventional bottom receiving structure, the entire thickness of the floor panel 15 is generated as a step as it is. In particular, since the thickness of the floor panel 15 is likely to vary, a step is likely to appear in the conventional structure, but a step is difficult to occur in the present structure. When 3000N panels and 5000N panels having different thicknesses are adjacent to each other, a spacer having a thickness difference is sandwiched between the panel placement surface 23 and the cushion rubber 24 so that the panels are flush with each other. Easy to do.

取付螺合部１７は、パネル受け部材２の下面中央に円筒体として形成されている。この取付螺合部１７の内面には、前記脚部７の外周面に形成された雄ネジ部１２と螺合し前記支柱ベース１に対する高さ位置を調整自在とする第３螺合部である雌ネジ部３５が形成されている。この取付螺合部１７の雌ネジ部３５と脚部７の雄ネジ部１２とを螺合させることにより、パネル受け部材２を、支柱ベース１に対して所望の高さ位置に調整することができる。   The mounting screw portion 17 is formed as a cylindrical body at the center of the lower surface of the panel receiving member 2. On the inner surface of the mounting screw 17, there is a third screwed portion that is screwed with a male screw portion 12 formed on the outer peripheral surface of the leg portion 7 so that the height position with respect to the column base 1 can be adjusted. A female screw part 35 is formed. The panel receiving member 2 can be adjusted to a desired height position with respect to the column base 1 by screwing the female screw part 35 of the mounting screw part 17 and the male screw part 12 of the leg part 7 together. it can.

「パネル固定部材」
パネル固定部材３は、図１から図５に示すように、フロアパネル１５の引掛部２５を前記パネル載掛部１９の段差部２８との間で挟持するパネル押圧部２９と、脚部７の先端に形成された孔部１０に挿入され雌ネジ部１１と螺合してパネル押圧部２９の高さ位置を調整自在とする第４螺合部である固定ボルト３０とからなる。 Panel fixing member
As shown in FIGS. 1 to 5, the panel fixing member 3 includes a panel pressing portion 29 that holds the hooking portion 25 of the floor panel 15 between the stepped portion 28 of the panel mounting portion 19, and the leg portion 7. The fixing bolt 30 is a fourth screwing portion that is inserted into the hole portion 10 formed at the tip and screwed into the female screw portion 11 so that the height position of the panel pressing portion 29 can be adjusted.

パネル押圧部２９は、前記フロアパネル１５の引掛部２５を押さえる引掛部押さえ面２９ａを下端部に有した円盤体として形成されている。このパネル押圧部２９は、引掛部２５を段差部２８とにより上下方向から挟み込むことで、該引掛部２５を挟持させる。そして、このパネル押圧部２９の中心には、固定ボルト３０を挿入させるための貫通孔３１が形成されている。   The panel pressing portion 29 is formed as a disk body having a hooking portion pressing surface 29a for pressing the hooking portion 25 of the floor panel 15 at the lower end portion. The panel pressing portion 29 sandwiches the hook portion 25 by sandwiching the hook portion 25 with the stepped portion 28 from above and below. A through hole 31 for inserting the fixing bolt 30 is formed at the center of the panel pressing portion 29.

固定ボルト３０は、脚部７の先端に形成された孔部１０に挿入され、その外周面に形成した雄ネジ部３２を該孔部１０の雌ネジ部１１と螺合させている。この固定ボルト３０を締め付ける方向に回すと、パネル固定部材３はパネル受け部材２側へとねじ込まれて行き、段差部２８に載掛けされた引掛部２５を、前記パネル押圧部２９とによって挟持する。逆に、固定ボルト３０を緩める方向に回すと、パネル固定部材３はパネル受け部材２と離れる方向に上昇し、前記引掛部２５の挟持状態を開放する。なお、固定ボルト３０の基端部には、例えばドライバーによって固定ボルト３０をねじ込むための十字形状のネジ回し溝３３が形成された皿状のネジ頭部３４が設けられている。   The fixing bolt 30 is inserted into the hole 10 formed at the tip of the leg 7, and the male screw part 32 formed on the outer peripheral surface thereof is screwed with the female screw part 11 of the hole 10. When the fixing bolt 30 is turned in the tightening direction, the panel fixing member 3 is screwed to the panel receiving member 2 side, and the hooking portion 25 placed on the step portion 28 is clamped by the panel pressing portion 29. . On the other hand, when the fixing bolt 30 is turned in the loosening direction, the panel fixing member 3 rises in a direction away from the panel receiving member 2, and the hooking portion 25 is released. The base end portion of the fixing bolt 30 is provided with a countersunk screw head 34 in which a cross-shaped screwing groove 33 for screwing the fixing bolt 30 with a screwdriver is formed, for example.

このように、固定ボルト３０を、アルミダイキャストによって一体化した支柱ベース１の先端部に形成した雌ネジ部１１に螺合させれば、当該支柱ベース１がしっかりしていることからがたつきなく強固にフロアパネル１５を固定させることができる。   In this way, if the fixing bolt 30 is screwed into the female screw portion 11 formed at the tip end portion of the column base 1 integrated by aluminum die casting, the column base 1 is firmly rattled. And the floor panel 15 can be firmly fixed.

「固定部材」
固定部材４は、図１及び図２に示すように、支柱ベース１に対するパネル受け部材２の高さ位置を固定するもので、脚部７の外周面に形成された雄ネジ部１２と螺合する第５螺合部である雌ネジ部３６を有した固定部３７と、この固定部３７から延在して形成されたレバー部３８とからなる。 `` Fixing member ''
As shown in FIGS. 1 and 2, the fixing member 4 fixes the height position of the panel receiving member 2 with respect to the column base 1, and is screwed with a male screw portion 12 formed on the outer peripheral surface of the leg portion 7. The fixing portion 37 has a female screw portion 36 which is a fifth screwing portion, and a lever portion 38 formed extending from the fixing portion 37.

かかる固定部材４は、レバー部３８を回して所定高さに仮保持されたパネル受け部材２の下端部に固定部３７を圧接させることにより、当該パネル受け部材２を回転不可能なロック状態とする。これにより、パネル受け部材２を確実に所定高さ位置に保持させることができる。この固定部材４のレバー部３８を回転させる操作は、専用工具を必要とすることなく簡単に手（指）で操作することができる。このため、施工時にレバー部３８を金槌で叩く必要がないことから音を立てずに静かに施工することができる。したがって、現場作業者や現場近隣の人達にも迷惑を掛けなく済む。   The fixing member 4 rotates the lever portion 38 and presses the fixing portion 37 against the lower end portion of the panel receiving member 2 that is temporarily held at a predetermined height so that the panel receiving member 2 is in a non-rotatable locked state. To do. Thereby, the panel receiving member 2 can be reliably held at a predetermined height position. The operation of rotating the lever portion 38 of the fixing member 4 can be easily operated by hand (finger) without requiring a dedicated tool. For this reason, since it is not necessary to hit the lever part 38 with a hammer during construction, the construction can be performed silently without making a noise. Therefore, it does not cause trouble for field workers and people near the site.

『フロアパネルの敷設方法』
次に、上述のように構成された二重床用支柱構造を使用してフロアパネル１５を敷設する施工方法について説明する。ここでの施工工程は一例であり、その手順に関しては以下の各工程の順番を多少入れ替えることもできる。 "How to lay a floor panel"
Next, a construction method for laying the floor panel 15 using the double floor support structure configured as described above will be described. The construction process here is an example, and the order of the following processes can be slightly changed with respect to the procedure.

先ず、上述のように構成された二重床用支柱構造を床面５に置く。次に、パネル受け部材２を支柱ベース１に対して所定高さ位置となるように調整する。すなわち、パネル受け部材２を時計回り方向または反時計回り方向に回転させることにより、脚部７の外周面に形成された雄ネジ部１２に取付螺合部１７の内面に形成した雌ネジ部３５を螺合させて、該パネル受け部材２の前記支柱ベース１に対する高さを上下に調整する。パネル受け部材２の支柱ベース１に対する高さ位置は、図５に示すように、床面５からフロアパネル１５のコーナー下面１５ａまでの垂直距離（高さ）Ｈが所定寸法となるようにする。   First, the double floor support structure configured as described above is placed on the floor surface 5. Next, the panel receiving member 2 is adjusted to a predetermined height position with respect to the column base 1. That is, by rotating the panel receiving member 2 in the clockwise direction or the counterclockwise direction, the female screw portion 35 formed on the inner surface of the mounting screw portion 17 on the male screw portion 12 formed on the outer peripheral surface of the leg portion 7. And the height of the panel receiving member 2 with respect to the column base 1 is adjusted up and down. As shown in FIG. 5, the vertical position (height) H from the floor surface 5 to the corner lower surface 15a of the floor panel 15 is set to a predetermined dimension with respect to the height position of the panel receiving member 2 with respect to the support base 1.

パネル受け部材２の支柱ベース１に対する高さが決まったらベース部６の底面６ａに接着剤を塗布した後、この二重床用支柱構造を床面５の所定位置に固定する。次に、パネル受け部材２の支柱ベース１に対する高さ位置が変動しないように、固定部材４によって当該パネル受け部材２を回転不可能にロックして前記所定高さ位置を保持させる。すなわち、この固定部材４のレバー部３８を作業者が握り、該レバー部３８を回転させて固定部３７をパネル受け部材２の取付螺合部１７の下端部に当接させる。これにより、パネル受け部材２は、この固定部材４によって支柱ベース１に対する高さ位置が位置決め固定されることになる。   After the height of the panel receiving member 2 with respect to the support base 1 is determined, an adhesive is applied to the bottom surface 6 a of the base portion 6, and then the double floor support structure is fixed to a predetermined position on the floor 5. Next, the panel receiving member 2 is locked by the fixing member 4 so as not to rotate so that the height position of the panel receiving member 2 with respect to the column base 1 does not vary, and the predetermined height position is held. That is, the operator grasps the lever portion 38 of the fixing member 4 and rotates the lever portion 38 to bring the fixing portion 37 into contact with the lower end portion of the mounting screw portion 17 of the panel receiving member 2. Accordingly, the height position of the panel receiving member 2 with respect to the column base 1 is positioned and fixed by the fixing member 4.

次に、この二重床用支柱構造の床面５に対する固定を確実なものとするために、ベース部６に形成されたボルト挿通孔９にボルトを挿通させ床面５に打ち込む。これで、二重床用支柱構造が確実に床面５に対して固定される。   Next, in order to secure the double floor support structure to the floor surface 5, a bolt is inserted into the bolt insertion hole 9 formed in the base portion 6 and driven into the floor surface 5. Thus, the double floor support structure is securely fixed to the floor surface 5.

次に、位置決め固定された二重床用支柱構造に対してフロアパネル１５を敷設する。フロアパネル１５の敷設に際しては、フロアパネル１５のコーナー部分に形成された引掛部２５をパネル載掛部１９の段差部２８に係合させて、このフロアパネル１５をパネル受け部材２の上に載せる。すると、フロアパネル１５の引掛部２５は、パネル載掛部１９の段差部２８に係合され、フロアパネル１５のコーナー下面１５ａは、パネル補助受け部２０に対して若干の隙間Ｓを有してパネル補助受け部２０上に載置される。 Next, the floor panel 15 is laid on the double-floor strut structure positioned and fixed. In the laying of the floor panel 15, by engaging the hook portion 25 formed at a corner portion of the floor panel 15 to the stepped portion 28 of the panel Nokaka portion 19, placed on the response to this floor panel 15 panel members 2 . Then, the hooking portion 25 of the floor panel 15 is engaged with the stepped portion 28 of the panel mounting portion 19, and the corner lower surface 15 a of the floor panel 15 has a slight gap S with respect to the panel auxiliary receiving portion 20. It is placed on the panel auxiliary receiving part 20.

次に、４枚のフロアパネル１５を４箇所のパネル載掛部１９にそれぞれ配置し終えたらパネル固定部材３で引掛部２５を確実に固定する。すなわち、ドライバーを使用して固定ボルト３０を脚部７の先端部に形成した孔部１０の雌ネジ部１１にねじ込み、パネル押圧部２９の下面に形成した引掛部押さえ面２９ａを段差部２８に係合された引掛部２５に押し付け、該段差部２８とパネル押圧部２９とで引掛部２５を挟持させる。これにより、フロアパネル１５をパネル受け部材２にがたつき無く固定させることができる。   Next, when the four floor panels 15 are respectively disposed on the four panel mounting portions 19, the hooking portions 25 are securely fixed by the panel fixing members 3.

『本実施の形態の効果』
以上のように構成された二重床用支柱構造では、ベース部６と脚部７を一体化した支柱ベース１と、この支柱ベース１に対してその高さ位置を調整自在とするパネル受け部材２と、該パネル受け部材２とでフロアパネル１５を挟持して固定するパネル固定部材３と、所望高さ位置にあるパネル受け部材２の位置を固定する固定部材４とからなる僅か４つの構成部品で構成しているので、従来構造に比べて部品点数を削減することができると共に組立工数も減らせることができ、低コスト化を実現できる。 “Effects of this embodiment”
In the double-floor support structure configured as described above, the support base 1 in which the base portion 6 and the leg portion 7 are integrated, and the panel receiving member whose height position is adjustable with respect to the support base 1. 2 and a panel fixing member 3 for holding and fixing the floor panel 15 between the panel receiving member 2 and a fixing member 4 for fixing the position of the panel receiving member 2 at a desired height position. Since it is composed of parts, the number of parts can be reduced as compared with the conventional structure, and the number of assembling steps can be reduced, thereby realizing cost reduction.

また、本実施の形態の二重床用支柱構造では、ベース部６の底面６ａを床面５と密着する略平坦面としているので、接着剤を薄く且つ均一に塗布することができ、床面５に対する接合強度を大幅に高めることができる。   Further, in the double floor support structure of the present embodiment, the bottom surface 6a of the base portion 6 is a substantially flat surface that is in close contact with the floor surface 5, so that the adhesive can be applied thinly and uniformly, and the floor surface The bonding strength to 5 can be greatly increased.

また、本実施の形態の二重床用支柱構造では、ベース部６を外周部から脚部７へと向かうに従ってその厚みを次第に厚くしているので、地震などによる水平荷重に対する強度を高めることができ、フロアパネル１５を支える支柱ベース１の機械的強度を向上させることができる。   In addition, in the double floor support structure of the present embodiment, the thickness of the base portion 6 is gradually increased from the outer peripheral portion toward the leg portion 7, so that the strength against a horizontal load due to an earthquake or the like can be increased. The mechanical strength of the column base 1 that supports the floor panel 15 can be improved.

また、本実施の形態の二重床用支柱構造では、脚部７を、先端からベース部６へと向かうに従ってその直径を次第に大きくした略円筒体としているので、座屈荷重に強く、座屈し難くなる。さらに、脚部７を中空構造としているので、調整代を長く確保することができる。   In the double-floor support structure of the present embodiment, the leg portion 7 is a substantially cylindrical body whose diameter is gradually increased from the tip toward the base portion 6, so that it is strong against buckling load and buckled. It becomes difficult. Furthermore, since the leg portion 7 has a hollow structure, a long adjustment allowance can be secured.

また、本実施の形態の二重床用支柱構造では、脚部７からベース部６にかけて補強用のリブ１４を形成したことにより、支柱ベース１の機械的強度が大幅に向上し、耐荷重性能を向上させることができる。さらにこれに加えて、ベース部６と脚部７を一体化しているので、支柱ベース１の機械的強度をより一層向上させることができる。その結果、支柱ベース１の強度が向上することからフロアパネル１５のパネル薄板化と軽量化を図ることが可能となる。   Further, in the double-floor support structure of the present embodiment, the reinforcing rib 14 is formed from the leg portion 7 to the base portion 6, so that the mechanical strength of the support base 1 is greatly improved and the load bearing performance is improved. Can be improved. In addition, since the base portion 6 and the leg portion 7 are integrated, the mechanical strength of the column base 1 can be further improved. As a result, since the strength of the support base 1 is improved, it is possible to reduce the thickness and weight of the floor panel 15.

また、本実施の形態の二重床用支柱構造では、少なくとも支柱ベース１及びパネル受け部材２を、表面処理が必要無くしかも錆びの発生の無いアルミダイキャストで形成しているので、従来のような鋼板にメッキを施すことによって発生するウィスカや六価クロム含有を回避することができる。   Further, in the double-floor support structure of the present embodiment, at least the support base 1 and the panel receiving member 2 are formed by aluminum die casting that does not require surface treatment and does not generate rust. It is possible to avoid whisker and hexavalent chromium content generated by plating a steel plate.

また、本実施の形態の二重床用支柱構造では、フロアパネル１５の引掛部２５を段差部２８に引っ掛けてパネル載置面２３に載せ、パネル固定部材３のパネル押圧部２９とでこの引掛部２５を挟持して固定するつば受け構造であるので、従来構造のようにパネル底面を受けるものではないことからパネル段差は板厚分の差しか発生せず、パネル間段差を減少させることができる。   In the double floor support structure of the present embodiment, the hooking portion 25 of the floor panel 15 is hooked on the stepped portion 28 and placed on the panel mounting surface 23, and this hooking is performed with the panel pressing portion 29 of the panel fixing member 3. Since the flange receiving structure that clamps and fixes the portion 25 does not receive the bottom surface of the panel as in the conventional structure, the panel step does not occur as much as the plate thickness, and the step difference between the panels can be reduced. it can.

また、本実施の形態の二重床用支柱構造では、つば受け構造であるため、支柱軸芯からフロアパネル１５を載掛する位置までの水平距離Ｌ（図５参照）を短くすることができ、支柱ベース１に掛かるモーメントを大幅に減少させることができる。これにより、パネル受けのがたつき抑制機構又は固定機構を別途用意することを防止できる。また、この水平距離Ｌを短くすることができることからパネル受け形状を小さく、軽量化することもできる。   In addition, since the double floor support structure of the present embodiment is a collar receiving structure, the horizontal distance L (see FIG. 5) from the support core to the position where the floor panel 15 is placed can be shortened. The moment applied to the support base 1 can be greatly reduced. Thereby, it is possible to prevent separately providing a rattling suppressing mechanism or a fixing mechanism of the panel receiver. Further, since the horizontal distance L can be shortened, the panel receiving shape can be reduced and the weight can be reduced.

また、本実施の形態の二重床用支柱構造では、固定部材４を金槌で叩かなくても簡単にレバー部３８を握って該固定部材４を回転させることができるため、フロアパネル敷設時の金属打音を無くすことができる。   Further, in the double-floor support structure of the present embodiment, the fixing member 4 can be easily rotated by grasping the lever portion 38 without hitting the fixing member 4 with a hammer. Metal hitting sound can be eliminated.
